Definitions
- the invention relates to a conveyor belt stripping device for a conveyor belt of a conveyor system and to a component of such a conveyor belt stripping device, namely a displacement guide for the attachment of a stripping segment to a support shaft of such a conveyor belt stripping device.
- Conveyor systems use a moving conveyor belt for transporting bulk material, such as sand, gravel and coal, from one location to another location.
- bulk material such as sand, gravel and coal
- a conveyor belt stripping device of the type discussed serves for the purpose of stripping the remaining bulk material adhering to the conveyor belt
- a first conveyor belt stripping device is normally situated directly at the deflection roller of the conveyor belt as a so-called primary stripper.
- a secondary stripper is mostly also situated downstream of the primary stripper in the running direction of the conveyor belt on the lower run of the conveyor belt.
- the mostly multiple stripping segments of a conveyor belt stripping device which stripping segments are arranged side by side, are fastened in an interchangeable manner to a support shaft which is mostly rotatable, frequently additionally also linearly adjustable and extends transversely to the conveyor belt.
- a tensioning device or in each case one tensioning device which comprises a lever structure or prestressed springs in order to generate the necessary prestressing, is connected to one or to both ends of the support shaft.
- a tensioning device also comprises a drive motor. The drive motor is then actuated by an electric or electronic control unit
- the starting point for the teaching of the present invention is a conveyor belt stripping device where improved interchangeability of the stripping segments has already been realized. (DE 20 2017 003 979 U1).
- a stripping segment for attaching to a support shaft of the conveyor belt stripping device is provided in the case of said conveyor belt stripping device.
- the stripping segment has a holding end, which is connectable to the support shaft in a positive locking manner and transmits torque, and a stripping end which is spaced therefrom and is movable into abutment with the conveyor belt.
- a displacement guide is integrally realized at the holding end.
- the holding end can be releasably connected to a displacement guide.
- the stripping segment is attachable to the support shaft in a positive locking manner so as to transmit torque and so as to be displaceable in the longitudinal direction of the support shaft.
- the holding end and the displacement guide comprise transverse sides which, in the state where the stripping segment is attached to the support shaft, extend transversely to the longitudinal direction of the support shaft.
- the stripping segment comprises, on both transverse sides, connection elements, by way of which two stripping segments arranged side by side on the support shaft are operatively couplable together in the longitudinal direction.
- the stripping segments when they are attached to the support shaft side by side, are all coupled together in this way.
- All coupled stripping segments are entrained when the foremost stripping segment is pulled out in this way.
- one stripping segment has been pulled out so far that it is no longer connected to the support shaft, it can be decoupled from the remaining coupled stripping segments and removed individually to the side.
- it has been shown that the forces to be applied when pulling laterally on all stripping segments that are connected together are very high.
- the problem underlying the teaching of the present invention is consequently to improve the previously described conveyor belt stripping device with regard to manageability.
- the conveyor belt stripping device has a support shaft and at least two displacement guides which are arranged side by side on the support shaft in a positive locking manner so as to transmit torque.
- Each of the two displacement guides is displaceable in the longitudinal direction of the support shaft once a fastening device has been released and is connected to a holding end of a stripping segment, wherein the stripping segment comprises a stripping end which is spaced from the holding end and is movable to abut the conveyor belt.
- the two displacement guides are operatively couplable together in the longitudinal direction of the support shaft by means of a connection device.
- the basic idea of the present invention consists in designing the conveyor belt stripping device in such a manner that the one displacement guide is able to be spatially removed from the displacement guide coupled with it and, where applicable, further displacement guides coupled with the other displacement guide (and consequently also the respective stripping segments), whilst the one displacement guide is arranged on the support shaft, in particular on a centre piece of the support shaft, preferably without displacing the displacement guides that are still coupled.
- the displacement guides are therefore separable into singles as it were still on the support shaft. This improves the manageability of the conveyor belt stripping device.
- the forces to be applied for singling out a stripping segment are lower than the forces to be applied for displacing all coupled stripping segments. What is more, where the stripping segments are contaminated, the forces to be applied for displacing individual stripping segments are lower than the forces to be applied for displacing all coupled stripping segments.
- the one displacement guide in the state coupled with the other displacement guide, is displaceable along the longitudinal direction of the support shaft to a predefined distance from the other displacement guide and then is displaceable along the longitudinal direction of the support shaft at the predefined distance to the other displacement guide together with the other displacement guide on account of the coupling by means of the connection device.
- the one of the two displacement guides in the state coupled with the other displacement guide, is preferably displaceable by means of the connection device along the longitudinal direction of the support shaft to the predefined distance from the other displacement guide and then is displaceable by means of the connection device along the longitudinal direction of the support shaft at the predefined distance to the other displacement guide together with the other displacement guide on account of the coupling by means of the connection device.

Abstract
Description
- The invention relates to a conveyor belt stripping device for a conveyor belt of a conveyor system and to a component of such a conveyor belt stripping device, namely a displacement guide for the attachment of a stripping segment to a support shaft of such a conveyor belt stripping device.
- Conveyor systems use a moving conveyor belt for transporting bulk material, such as sand, gravel and coal, from one location to another location. When the bulk material falls down from the conveyor belt at a deflection roller at the end, sometimes residual bulk material sticks to the conveyor belt. A conveyor belt stripping device of the type discussed serves for the purpose of stripping the remaining bulk material adhering to the conveyor belt
- A first conveyor belt stripping device is normally situated directly at the deflection roller of the conveyor belt as a so-called primary stripper. A secondary stripper is mostly also situated downstream of the primary stripper in the running direction of the conveyor belt on the lower run of the conveyor belt.
- The mostly multiple stripping segments of a conveyor belt stripping device, which stripping segments are arranged side by side, are fastened in an interchangeable manner to a support shaft which is mostly rotatable, frequently additionally also linearly adjustable and extends transversely to the conveyor belt.
- A tensioning device or in each case one tensioning device, which comprises a lever structure or prestressed springs in order to generate the necessary prestressing, is connected to one or to both ends of the support shaft. Occasionally, a tensioning device also comprises a drive motor. The drive motor is then actuated by an electric or electronic control unit
- An example of a conveyor belt stripping device of the type discussed is the object of
document DE 20 2014 007 229 U1. Variants for the attachment of stripping segments to a support shaft of a conveyor belt stripping device can additionally be found in the prior art inDE 20 2009 004 182 U1 andDE 20 2012 010 945 U1. - The starting point for the teaching of the present invention is a conveyor belt stripping device where improved interchangeability of the stripping segments has already been realized. (DE 20 2017 003 979 U1).
- A stripping segment for attaching to a support shaft of the conveyor belt stripping device is provided in the case of said conveyor belt stripping device. The stripping segment has a holding end, which is connectable to the support shaft in a positive locking manner and transmits torque, and a stripping end which is spaced therefrom and is movable into abutment with the conveyor belt. A displacement guide is integrally realized at the holding end. As an alternative to this, the holding end can be releasably connected to a displacement guide. By means of the displacement guide, the stripping segment is attachable to the support shaft in a positive locking manner so as to transmit torque and so as to be displaceable in the longitudinal direction of the support shaft. The holding end and the displacement guide comprise transverse sides which, in the state where the stripping segment is attached to the support shaft, extend transversely to the longitudinal direction of the support shaft. The stripping segment comprises, on both transverse sides, connection elements, by way of which two stripping segments arranged side by side on the support shaft are operatively couplable together in the longitudinal direction.
- The stripping segments, when they are attached to the support shaft side by side, are all coupled together in this way. As a result, it is possible to remove the stripping segments from the support shaft in the longitudinal direction by pulling only on the foremost one, that is to say the laterally outermost stripping segment under the conveyor belt or the displacement guide thereof. All coupled stripping segments are entrained when the foremost stripping segment is pulled out in this way. When one stripping segment has been pulled out so far that it is no longer connected to the support shaft, it can be decoupled from the remaining coupled stripping segments and removed individually to the side. In practice, it has been shown that the forces to be applied when pulling laterally on all stripping segments that are connected together are very high. This naturally applies all the more the higher the number of coupled stripping segments and the heavier the coupled stripping segments. Particularly high forces are to be applied in the typical case where the stripping segments are contaminated as a result of stripping bulk materials. Here, the contamination frequently gives rise to high connection forces between the stripping segments amongst themselves and/or between the stripping segments and the support shaft
- The problem underlying the teaching of the present invention is consequently to improve the previously described conveyor belt stripping device with regard to manageability.
- The problem presented previously is solved by a conveyor belt stripping device according to
Claim 1. Preferred designs and further developments of the conveyor belt stripping device according to the invention are the object of the relevant subclaims. - The conveyor belt stripping device according to
Claim 1 has a support shaft and at least two displacement guides which are arranged side by side on the support shaft in a positive locking manner so as to transmit torque. Each of the two displacement guides is displaceable in the longitudinal direction of the support shaft once a fastening device has been released and is connected to a holding end of a stripping segment, wherein the stripping segment comprises a stripping end which is spaced from the holding end and is movable to abut the conveyor belt. The two displacement guides are operatively couplable together in the longitudinal direction of the support shaft by means of a connection device. - The basic idea of the present invention consists in designing the conveyor belt stripping device in such a manner that the one displacement guide is able to be spatially removed from the displacement guide coupled with it and, where applicable, further displacement guides coupled with the other displacement guide (and consequently also the respective stripping segments), whilst the one displacement guide is arranged on the support shaft, in particular on a centre piece of the support shaft, preferably without displacing the displacement guides that are still coupled. The displacement guides are therefore separable into singles as it were still on the support shaft. This improves the manageability of the conveyor belt stripping device. In particular, the forces to be applied for singling out a stripping segment are lower than the forces to be applied for displacing all coupled stripping segments. What is more, where the stripping segments are contaminated, the forces to be applied for displacing individual stripping segments are lower than the forces to be applied for displacing all coupled stripping segments.
- To this end, the one displacement guide, in the state coupled with the other displacement guide, is displaceable along the longitudinal direction of the support shaft to a predefined distance from the other displacement guide and then is displaceable along the longitudinal direction of the support shaft at the predefined distance to the other displacement guide together with the other displacement guide on account of the coupling by means of the connection device.

FIG. 1 shows a schematic view of a detail of aconveyor belt 19 of a conveyor system, on whichbulk material 20 is situated. Saidconveyor belt 19 runs from back left to front right inFIG. 1 . It is turned around at adeflection roller 21 so that its lower belt portion runs back from front right to back left, that is to say in the direction of the starting point - A conveyor belt stripping device with a
support shaft 1 can be seen below theconveyor belt 19 and not far from thedeflection roller 21. - A
holder 22 for thesupport shaft 1 can be seen in each case on the left and the right inFIG. 1 with thesupport shaft 1 only shown by broken lines. Thesupport shaft 1 is rotatably mounted here in theholders 22. A tensioning device which applies a suitable prestressing force on thesupport shaft 1 is not shown inFIG. 1 . The prior art is referred to in this respect. - Three stripping
segments 4 are shown on thesupport shaft 1 inFIG. 1 as an example. Each strippingsegment 4 has a strippingend 6 which comes to abut against theconveyor belt 19 and a holdingend 5 which is connected in a positive locking manner to thesupport shaft 1 so as to transmit torque and is at spacing from the strippingend 6. - In the example of the prior art shown here, each stripping
segment 4 has a body of polyurethane in which the strippingend 6, in the form of a support rod with a stripping lip at the end, is mounted. The body of the strippingsegment 4 continues in the holdingend 5, which is inserted into a corresponding receiving means in thesupport shaft 1. This is only one of various possibilities in the prior art for attaching a strippingsegment 4 to thesupport shaft 1 of the conveyor belt stripping device. -
FIG. 2 shows a schematic representation of a further prior art, namely a side view of a typical conveyor belt stripping device on aconveyor belt 19. It is possible to see a typicalprimary stripper 23 on the deflection roller 3 on the right inFIG. 2 and a typicalsecondary stripper 24 which cooperates from below with the lower returning portion of theconveyor belt 19 on the left inFIG. 2 . Reference is also made to the prior art in this respect. -
FIG. 3 shows a schematic representation of a perspective view of the parts, seen here as essential, of a first exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 4 to 6 show further views of said conveyor belt stripping device. The conveyor belt stripping device has asupport shaft 1 and eightdisplacement guides 2 which are arranged side by side on thesupport shaft 1 in a positive locking manner so as to transmit torque. - Each of the displacement guides 2 is displaceable in the longitudinal direction L of the
support shaft 1 once a fastening device, not shown here, has been released and is connected to a holdingend 5 of a strippingsegment 4. As an alternative to this, the displacement guides 2 can be realized integrally with the holdingend 5. The strippingsegment 4 must then be a strippingsegment 4 which is specially adapted to the present application. - Each stripping
segment 4 comprises a strippingend 6 which is at a spacing from the holdingend 5 and is movable into abutment with the conveyor belt. - These are stripping
segments 4 of aprimary stripper 23 in this case. As an alternative to this, they can be strippingsegments 4 of a secondary stripper 24 (seeFIGS. 7 to 11 ). - The displacement guides 2 are operatively couplable and here are also coupled together in the longitudinal direction L of the
support shaft 1 by means of a connection device 7. - In the case of the preferred exemplary embodiment shown here, the connection device 7 has precisely one
connection element 9 which extends over all displacement guides 2 and beyond. Theconnection element 9 here is a chain. - The chain preferably comprises metal or consists of metal. In a preferred manner, it is a round link chain.
- Each of the displacement guides 2 has
longitudinal sides 10A, 10B which, in the state attached to thesupport shaft 1, extend along the longitudinal direction L of thesupport shaft 1. The connection device 7 is fixed to alongitudinal side 10A of eachdisplacement guide 2 in each case by means of a fixingelement 8. The length of thechain 9 or of the portion of thechain 9 between the fixingelements 8 of twodisplacement guides 2 arranged directly side by side (that is to say adjacent) is greater than the distance between the fixingelements 8 of said twodisplacement guides 2 when said twodisplacement guides 2 abut against one another. The respective predefined distance depends on the length of thechain 9 or of the portion of thechain 9 between in each case two adjacent displacement guides 2. - In the case of the preferred exemplary embodiment shown in
FIG. 3 , thefirst displacement guide 2 proceeding from the left, in the state coupled with thesecond displacement guide 2 proceeding from the left (thedisplacement guide 2 arranged at a certain distance to the right next to thefirst displacement guide 2 inFIG. 3 ), is displaceable as a result of exertion of a tensile force on thechain 9 to the predefined distance from thesecond displacement guide 2 along the longitudinal direction L of thesupport shaft 1. The exertion of the tensile force on thechain 9 is effected here to the left along the longitudinal direction L of thesupport shaft 1. Thesecond displacement guide 2, in the state coupled with thethird displacement guide 2 proceeding from the left (thedisplacement guide 2 abutting against thesecond displacement guide 2 on the right inFIG. 3 ) is once again displaceable as a result of exertion of a tensile force on thechain 9 to the predefined distance from thethird displacement guide 2 along the longitudinal direction L of thesupport shaft 1. The same applies to the further displacement guides 2—up to the eighth displacement guide 2 (outside right). - The
first displacement guide 2 is therefore spatially removable from thesecond displacement guide 2 coupled with it and from the other displacement guides 2 whilst thefirst displacement guide 2 is arranged on thesupport shaft 1. This can occur such that thesecond displacement guide 2 and/or the further displacement guides 2 are not displaced at the same time. - As a result of corresponding repetition, displacement guides 2 which abut against one another can be separated into singles in this manner.
- It can be seen in
FIG. 3 that thefirst displacement guide 2 is arranged on thesupport shaft 1 at a certain distance from thesecond displacement guide 2. Said certain distance is smaller than the predefined distance. - If the first and the second displacement guides 2 have been separated out into singles, the
first displacement guide 2 is displaceable at the predefined distance to thesecond displacement guide 2 as a result of exertion of a tensile force on the chain 9 (to the left inFIG. 3 ) together with the second displacement guide along the longitudinal direction L of thesupport shaft 1 in the direction of the tensile force on account of the coupling by means of thechain 9. - An embodiment where the connection device comprises a further chain as second connection element is not shown, the further chain being fixed to the longitudinal side 10B of each
displacement guide 2 in each case by means of a fixingelement 8. -
FIG. 7 shows a schematic representation of a perspective view of the parts, seen here as essential, of a second exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 8 to 10 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized as the conveyor belt stripping device according to the first exemplary embodiment—with the difference that differently designed strippingsegments 4 are provided which are part of asecondary stripper 24. -
FIG. 11 shows a schematic representation of a perspective view of the parts, seen here as essential, of a third exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system. Compared to the conveyor belt stripping device according to the second exemplary embodiment,FIG. 11 only shows seven instead of eight displacement guides 2. In addition, a fastening device 3 is illustrated here as an example for all exemplary embodiments. - The fastening device 3 forms for the displacement guides 2 a left-hand stop which is situated on the
support shaft 1 and a right-hand stop which is situated on thesupport shaft 1. The right-hand stop inFIG. 11 is arranged and fixed during the mounting of the conveyor belt stripping device on thesupport shaft 1 so that the position thereof is no longer modifiable. The left-hand stop inFIG. 11 is arranged in a releasable manner on thesupport shaft 1. In the state fastened to thesupport shaft 1, the fastening device 3 blocks displacement of the displacement guides 2 in the longitudinal direction L of thesupport shaft 1. Once the fastening device 3 has been released, the left-hand stop is removable so that the displacement guides 2 are displaceable 2 in the longitudinal direction L of thesupport shaft 1. -
FIG. 12 shows a schematic representation of a perspective view of the parts, seen here as essential, of a fourth exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 13 to 15 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized basically as the conveyor belt stripping device according to the first exemplary embodiment. For reasons of simplification, no strippingsegments 4 are shown in the case of the fourth exemplary embodiment. -
Adapter 18 for the attachment of the holdingend 6 of a specific strippingsegment 4 is shown. With theadapter 18 designed in a corresponding manner, it is also possible to attach a standard strippingsegment 4 here as is disclosed in the prior art. - In the case of the preferred exemplary embodiment shown here, the precisely one
connection element 9 of the connection device 7 is a cable. Thecable 9 is fixed to alongitudinal side 10A of eachdisplacement guide 2 in each case by means of a fixingelement 8. Each fixing element is realized in a sleeve-shaped manner. - The statements concerning the chain of the first exemplary embodiment apply correspondingly to the cable of the fourth exemplary embodiment.
-
FIG. 16 shows a schematic representation of a perspective view of the parts, seen here as essential, of a fifth exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 17 to 19 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized basically as the conveyor belt stripping device according to the fifth exemplary embodiment. In the case of the preferred exemplary embodiment shown here, theconnection element 9 of the connection device 7 is once again a cable which is fixed to alongitudinal side 10A of eachdisplacement guide 2 in each case by means of a fixingelement 8. Each fixing element is a locking bolt. -
FIG. 20 shows a schematic representation of a perspective view of the parts, seen here as essential, of a sixth exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 21 to 23 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized basically as the conveyor belt stripping device according to the fourth exemplary embodiment. - In the case of the preferred exemplary embodiment shown here, the connection device 7 has
multiple connection elements 9. Eachconnection element 9 extends from alongitudinal side 10A of adisplacement guide 2 to alongitudinal side 10A of anadjacent displacement guide 2 or from the other longitudinal side 10B of adisplacement guide 2 to the other longitudinal side 10B of anadjacent displacement guide 2. A total of 14connection elements 9 are consequently provided here. - Each
connection element 9 is fixed to alongitudinal side 10A of adisplacement guide 2 and to alongitudinal side 10A of anadjacent displacement guide 2 in each case by means of a fixingelement 8 or to the other longitudinal side 10B of adisplacement guide 2 and to the other longitudinal side 10B of anadjacent displacement guide 2 in each case by means of a fixingelement 8. - The
connection elements 9 are in each case an elastic belt - In the case of the preferred exemplary embodiment shown in
FIG. 20 , thefirst displacement guide 2 proceeding from the right, in the state coupled with thesecond displacement guide 2 proceeding from the right (thedisplacement guide 2 arranged at a certain distance to the left next to thefirst displacement guide 2 inFIG. 20 ), is displaceable as a result of exertion of a tensile force on thefirst displacement guide 2 to the predefined distance from thesecond displacement guide 2 along the longitudinal direction L of thesupport shaft 1. The exertion of the tensile force on thedisplacement guide 2 is effected here to the right along the longitudinal direction L of thesupport shaft 1. - The
second displacement guide 2, in the state coupled with thethird displacement guide 2 proceeding from the right (thedisplacement guide 2 abutting against thesecond displacement guide 2 on the left inFIG. 20 ) is once again displaceable as a result of exertion of a tensile force on thedisplacement guide 2 to the predefined distance from thethird displacement guide 2 along the longitudinal direction L of thesupport shaft 1. The same applies to the further displacement guides 2—up to the eighth displacement guide 2 (outside left). - The respective predefined distance depends on the modulus of elasticity of the respective
elastic belt 9. - The
elastic belts 9 preferably comprise a modulus of elasticity of approximately 15 MPa (according to ISO 527) and/or a tensile strength of approximately 45 MPa (according to ISO 527). - If the first and the second displacement guides 2 have been separated out into singles, the
first displacement guide 2 is displaceable at the predefined distance to thesecond displacement guide 2 as a result of exertion of a tensile force on the displacement guide 2 (to the right in inFIG. 20 ) together with the second displacement guide along the longitudinal direction L of thesupport shaft 1 in the direction of the tensile force on account of the coupling by means of theelastic belt 9. -
FIG. 24 shows a schematic representation of a perspective view of the parts, seen here as essential, of a seventh exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 25 to 27 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized basically as the conveyor belt stripping device according to the fourth exemplary embodiment. - In the case of the preferred exemplary embodiment shown here, the connection device 7 has on each
displacement guide 2 twobolts 11 and twoconnection elements 9. Aconnection element 9 and abolt 11 are attached to thelongitudinal side 10A of therespective displacement guide 2. Afurther connection element 9 and afurther bolt 11 are attached to the other longitudinal side 10B of therespective displacement guide 2. - Each
connection element 9 comprises arecess 12. - The seventh exemplary embodiment is explained below by way of the design on the one
longitudinal side 10A of the displacement guides 2. The same applies to the design on the other longitudinal sides 10B of the displacement guides 2. - With two
displacement guides 2 in the coupled state, the twoconnection elements 9 of the onedisplacement guide 2 extend from the onelongitudinal side 10A of the onedisplacement guide 2 to theother displacement guide 2. Therecess 12 of theconnection element 9 on thelongitudinal side 10A of the onedisplacement guide 2, in the coupled state, receives thebolt 11 on thelongitudinal side 10A of theother displacement guide 2 in such a manner that thebolt 11 on thelongitudinal side 10A of theother displacement guide 2 is displaceable in therecess 12 of theconnection element 9 on thelongitudinal side 10A of the onedisplacement guide 2 along the longitudinal direction L of thesupport shaft 1 by the defined distance so that the onedisplacement guide 2 is displaceable as a result of exertion of a tensile force on the onedisplacement guide 2 to the predefined distance from theother displacement guide 2 along the longitudinal direction L of thesupport shaft 1. - The
recess 12 of theconnection element 9 on thelongitudinal side 10A of the onedisplacement guide 2 forms a stop for thebolt 11 on thelongitudinal side 10A of theother displacement guide 2. If thebolt 11 of theother displacement guide 2 strikes against therecess 12 of the onedisplaceable guide 2, part of a tensile force exerted on the onedisplaceable guide 2 is transmitted to theother displacement guide 2. Theother displacement guide 2 can thus be displaced to the predefined distance from afurther displacement guide 2 coupled with theother displacement guide 2 along the longitudinal direction L of thesupport shaft 1. The displacement guides 2 can be separated out into singles in this way. - If the two coupled displacement guides 2 looked at at the start have been separated into singles, they can be displaced together to the predefined distance with respect to one another along the longitudinal direction L of the
support shaft 1, as a result of exertion of a tensile force on the onedisplacement guide 2. -
FIG. 28 shows a schematic representation of a perspective view of the parts, seen here as essential, of an eighth exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 29 to 32 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized basically as the conveyor belt stripping device according to the fourth exemplary embodiment. - In the case of the preferred exemplary embodiment shown here, the connection device 7 has two
hollow cylinders 13 on eachdisplacement guide 2. The onehollow cylinder 13 is attached to the onelongitudinal side 10A of therespective displacement guide 2. The otherhollow cylinder 13 is attached to the other longitudinal side 10B of therespective displacement guide 2. Apiston 14 is arranged in each of the twohollow cylinders 13. - Each
hollow cylinder 13 has adelimiter 16 and eachpiston 14 has astop 15. In the case of the preferred exemplary embodiment shown here, thedelimiter 16 is formed by a narrowing of thehollow cylinder 13 at one of its ends and thestop 15 is formed by a widening of thepiston 14 at one of its ends. - The eighth exemplary embodiment is explained below by way of the design on the one
longitudinal side 10A of the displacement guides 2. The same applies to the design on the other longitudinal sides 10B of the displacement guides 2. - With two
displacement guides 2 in the coupled state, thepiston 14 on the onelongitudinal side 10A of the onedisplacement guide 2 is movable relative to thehollow cylinder 14 on the onelongitudinal side 10A of the onedisplacement guide 2 and is coupled with thehollow cylinder 13 on the onelongitudinal side 10A of theother displacement guide 2 in such a manner that theother displacement guide 2 is slidable away from the onedisplacement guide 2 along the longitudinal direction L of thesupport shaft 1 as a result of exertion of a tensile force on theother displacement guide 2 until thestop 15 of thepiston 14 on the onelongitudinal side 10A of the onedisplacement guide 2 abuts against thedelimiter 16 of thehollow cylinder 13 on the onelongitudinal side 10A of the onedisplacement guide 2 so that theother displacement guide 2 is displaceable to the predefined distance from the onedisplacement guide 2 along the longitudinal direction L of thesupport shaft 1 as a result of exertion of a tensile force on theother displacement guide 2. - The
piston 14 on the onelongitudinal side 10A of the onedisplacement guide 2 can be releasably connected for coupling, for example, with thehollow cylinder 13 on the onelongitudinal side 10A of theother displacement guide 2. In a particularly preferred manner, there is a plug-in connection here. To this end, thepiston 14 on the onelongitudinal side 10A of the onedisplacement guide 2 can project into thehollow cylinder 13 on the onelongitudinal side 10A of theother displacement guide 2 and can be locked by a pluggable locking element such as a spring split pin. - If the
stop 15 of thepiston 14 on the onelongitudinal side 10A of the onedisplacement guide 2 abuts against thedelimiter 16 of thehollow cylinder 13 on the onelongitudinal side 10A of the onedisplacement guide 2, part of a tensile force exerted on theother displacement guide 2 is thus transmitted to the onedisplacement guide 2. The onedisplacement guide 2 can thus be displaced to the predefined distance from afurther displacement guide 2 coupled with the onedisplacement guide 2 along the longitudinal direction L of thesupport shaft 1. The displacement guides 2 can be separated into singles in this way. - If the two coupled displacement guides 2 looked at at the start have been separated into singles, they can be displaced together at the predefined distance with respect to one another along the longitudinal direction L of the
support shaft 1, whilst thestop 15 of thepiston 14 on the onelongitudinal side 10A of the onedisplacement guide 2 abuts against thedelimiter 16 of thehollow cylinder 13 on the onelongitudinal side 10A of the onedisplacement guide 2, as a result of exertion of a tensile force on theother displacement guide 2. - In the case of the preferred exemplary embodiment shown here, each
hollow cylinder 13 extends over the entire length, running in the longitudinal direction of thesupport shaft 1, of the onelongitudinal side 10A of the associateddisplacement guide 2. The extension of eachpiston 14 in the longitudinal direction of thesupport shaft 1 is longer than the predefined distance. -
FIG. 33 shows a schematic representation of a perspective view of the parts, seen here as essential, of a ninth exemplary embodiment of a conveyor belt stripping device according to the invention for a conveyor belt of a conveyor system.FIGS. 34 to 36 show further views of said conveyor belt stripping device. Said conveyor belt stripping device is realized basically as the conveyor belt stripping device according to the fourth exemplary embodiment. - In the case of the preferred exemplary embodiment shown here, the connection device 7 has two
connection plates connection plate 17A is fixed to alongitudinal side 10A of the onedisplacement guide 2 so as to be rotatable by means of a fixingelement 8 and theother connection plate 17B is fixed to alongitudinal side 10A of theother displacement guide 2 so as to be rotatable by means of afurther fixing element 8. - The maximum extension of two
connection plates elements 8 of said twodisplacement guides 2 when said twodisplacement guides 2 abut against one another. - In the case of the preferred exemplary embodiment shown in
FIG. 33 , thefirst displacement guide 2 proceeding from the right, in the state coupled with thesecond displacement guide 2 proceeding from the right (thedisplacement guide 2 arranged at a certain distance to the left next to thefirst displacement guide 2 inFIG. 33 ), is displaceable to the predefined distance from thesecond displacement guide 2 along the longitudinal direction L of thesupport shaft 1 as a result of exertion of a tensile force on thefirst displacement guide 2. The exertion of the tensile force on thedisplacement guide 2 is effected here to the right along the longitudinal direction L of thesupport shaft 1. Thesecond displacement guide 2, in the state coupled with thethird displacement guide 2 proceeding from the right (thedisplacement guide 2 abutting against thesecond displacement guide 2 on the left inFIG. 33 ) is once again displaceable to the predefined distance from thethird displacement guide 2 along the longitudinal direction L of thesupport shaft 1 as a result of exertion of a tensile force on thesecond displacement guide 2. The same applies to the further displacement guides 2—up to the eighth displacement guide 2 (outside left). - The
first displacement guide 2 is therefore spatially removable from thesecond displacement guide 2 coupled with it and from the other displacement guides 2 whilst thefirst displacement guide 2 is arranged on thesupport shaft 1. This can occur such that thesecond displacement guide 2 and/or the further displacement guides 2 are not displaced at the same time. - As a result of corresponding repetition, displacement guides 2 which abut against one another can be separated into singles in this manner.
- It can be seen in
FIG. 33 that thefirst displacement guide 2 is arranged on thesupport shaft 1 at a certain distance from thesecond displacement guide 2. Said certain distance is smaller than the predefined distance. Theconnection plate 17A which is attached to thefirst displacement guide 2 and theconnection plate 17B which is connected to saidconnection plate 17A and is attached to thesecond displacement guide 2 have not reached their common maximum extension inFIG. 33 . - If the first and the second displacement guides 2 have been separated out into singles, the
first displacement guide 2 is displaceable at the predefined distance to thesecond displacement guide 2 as a result of exertion of a tensile force on the second displacement guide (to the right in inFIG. 33 ) together with the second displacement guide along the longitudinal direction L of thesupport shaft 1 in the direction of the tensile force on account of the coupling by means of theconnection plates - An embodiment where, for coupling in each case two adjacent displacement guides 2, the connection device has two further connection plates which are connected together in an articulated manner, wherein the one connection plate is fixed to the other longitudinal side 10B of the one
displacement guide 2 so as to be rotatable and the other connection plate is fixed to the other longitudinal side 10B of theother displacement guide 2 so as to be rotatable, is not shown. - The displacement guides 2 are realized as hollow profiles which are open on one side in
FIGS. 3 to 36 . -
FIGS. 3 to 36 show, apart from this, the displacement guides 2 with a fastening means 25, in particular a locking bolt, by means of which therespective displacement guide 2 with the strippingsegment 4 attached thereto is locked securely (but so as to be displaceable in the longitudinal direction L of the support shaft 1) on thesupport shaft 1. - As can be seen from the preceding realizations, an object of the invention is also a
displacement guide 2 per se, for the attachment of a strippingsegment 4 to asupport shaft 1 of a conveyor belt stripping device. Thedisplacement guide 2 according to the invention, in this case, is realized as one of the above-described displacement guides 2 of the conveyor belt stripping devices according to one of the above exemplary embodiments.
